TL;DR: In this article, the bending strength of reaction-sintered SiC (RS-SiC) was evaluated and the strength over 1000 MPa was obtained to control the residual Si size under 100 nm.

TL;DR: In this article, a hafnia-based thermal barrier coatings (TBC) was developed for the key technology of gas turbine and diesel engine applications, and the 7.5YSH was selected for coating material.

TL;DR: In this paper, a method of manufacturing fiber composite ceramic is presented, in which large number of BN-coated SiC fibers are gathered to form yarns, or yarns are woven to form a two-dimensional or three-dimensional fabric, and a preform is formed by the yarns or the fabric, a molten Si is impregnated into the compact to form an SiC matrix between fibers.

TL;DR: In this paper, the authors evaluated the hydrogen production efficiency of high temperature electrolysis (HTE) with a high temperature gas cooled reactor and found that the measured hydrogen production rate has good agreement with calculated HPR based on applied current.

TL;DR: In this paper, the leaching behavior of pressureless sintered and hotpressed Si3N4 containing Y2O3, Al 2O3 and AlN without additives was studied in 0.1M to 10M HCl aqueous solutions at 50° to 100°C.
